' SAM PLING DEVICE.

SPECIFICATION forming part of Letters Patent No. 651,607, dated June 12, 1900.

. Application filed May 4, 1899. Serial No. 715 ,558- (No model.)

To all whom it may concern:

Be it known that I, WILLIAM G. LOVERING, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, haveinvented a certain Iin.-' proved Sampling Device, of which the followingis a full, clear, and exact specification.

My improved sampling device is designed for the purpose of securing a representative sample from a bale of cotton or other fibrous material. At the present time samples of such bales are purely superficial and are only characteristic either of the external portions or of the interior portions of such bales. By means of my improved sampling device a sample can be secured which will be representative of the entire bulk of the bale, being composed of material drawn successively from the interior to the outer surface thereof.

The'object of my invention is to provide a simple and cheap device having this advantageous capacity.

In carrying out my invention I employ an essentially pointed tool adapted to be introduced into the bale and provided with one or more projections or teeth for engaging the material and Withdrawing a sample therefrom. Preferably a plurality of these projections or teeth are used, extending in a direction opposite to that in which the device is rotated or otherwise moved in being introduced into the bale, whereby no retardation will be ofiered to its introduction. In removing the device, however, either by ontirely unscrewing itor by giving it a partial or a complete reverse rotation and by then withdrawing it bodily or by simply withdrawing it directly the fingers or projections will engage the fibrous material at difierent por- 1 represents a general screw-like device having a handle 2 for rotating it and a suitable point 3 for facilitating the introduction into the bale. Any other formation of spirals may be adopted instead of the specific type shown, as will be obvious to those skilled in the arts relating to the manufacture and use of angers, post hole angers, gimlets, screws, corkscrews, &c. The screw portion of the device is provided with one or more fingers or teeth 4, perfectlypointed, as shown. These pointed fingers or teeth are out, pref erably, in the outer edge of the spiral forma tion and extend in a direction opposite to the 6 rotation of the screw in its introduction into the bale. This direction of rotation is indicated by the arrow in Fig. 2. It will be ob served that by rotating the handle 2 to turn the device in the direction of the arrow it will be forced into the bale to the desired depth, the fingers or projections at offering no especial opposition to this operation. In reversing the rotation of the device, however, for removing it the fingers or points 4 will be engaged with the fibrous material and each will remove a small sample thereof.

Instead of removing the device from the bale by reversing its entire original rotation it may be given a partial reverse rotation to first engage the points or fingers with the fibrous material and may then be Withdrawn bodily to secure a representative sample.

By providing the device with a series of fingers or points, as shown, arranged substantially equidistant throughout the entire length of the screw portion samples will be secured from the bale at varying depths from its surface, which samples in the aggregate will be truly representative of the entire bale. 0 If, however, only a single one of the points or fingers is used, or when only two of such points or fingers are used, they will be, preferably, disposed near the pointed end of the screw portion, whereby in their withdrawal 5 in passing outward through the bale material will be engaged thereby and removed. In this way a substantially-representative sample will be secured, although obviously not so effectively as when a large number of the points or fingers are employed, as explained.

Having now described my invention, what I claim as new therein, and desire to secure by Letters Patent, is as follows:

1. An improved sampling device, comprising a screw-like shank adapted to be engaged into a bale of fibrous material by a rotative action and a point or finger carried by said shank and disposed in a direction opposite to the engaging rotation thereof, substantially as set forth.

2. An improved sampling device, comprising a screw-like shank adapted to be engaged
